«Joseph Heller, an important & funny writer now dead, & I [Kurt Vonnegut] were at a party given by a billionaire on Shelter Island.
I said, “Joe, how does it make you feel to know that our host only yesterday may have made more money than your novel ‘Catch-22’
has earned in its entire history?”
& Joe said, “I’ve got something he can never have.”
& I said, “What on earth could that be, Joe?”
& Joe said, “The knowledge that I’ve got enough.”
Not bad! Rest in peace!»
